Diseases, Conditions, SyndromesThu, 18 Jun 2015 06:13:54 EDTnews353826825Cozy niches: Certain host cell environments make malaria parasites resistant to drugsOf the two species of Plasmodium parasites commonly infecting humans, P. vivax grows exclusively in immature red blood cells called reticulocytes. P. falciparum can infect reticulocytes, but it grows primarily in mature red blood cells (called erythrocytes) which make up 99% of red cells in circulation. A study published on June 4th in PLOS Pathogens shows that the different metabolic states of these human host cells provide different growth conditions for the respective parasites—and warn that, as a consequence, drugs that work against one Plasmodium species might fail to be effective against the other.http://medicalxpress.com/news/2015-06-cozy-niches-host-cell-environments.html

Chan School of Public Health and the Broad Institute have identified a protein on the surface of human red blood cells that serves as an essential entry point for invasion by the malaria parasite. The presence of this protein, called CD55, was found to be critical to the Plasmodium falciparum parasite's ability to attach itself to the red blood cell surface during invasion. This discovery opens up a promising new avenue for the development of therapies to treat and prevent malaria.http://medicalxpress.com/news/2015-05-malaria-parasite-essential-doorway-red.html

In a paper published in the American Journal of Hematology, the research team reports finding that higher levels of a measure routinely taken as part of the complete blood count - the extent of variation in the size of red blood cells - is caused by reduced clearance of aging cells from the bloodstream. Hundreds of studies since 2007 have found that elevations in this measure - called RDW for RBC (red blood cell) distribution width - predicted the development, progression and risk of death from many conditions.http://medicalxpress.com/news/2015-04-decreased-red-blood-cell-clearance.html
